T all whom it may concern:

Be '-'t known that I, Ln Roar MERRow,

- a; citizen ofthe United States, residing at Springfield, in the county of Clark and Stateof Ohio, have invented new and use- ,ful Improvements in Dumping Devices, of

a dumping vehicle, particularly the use'of a dumping mechanism in connec- 3 is a side by means of a chain 15 to a sprocket 16 with board of the dumping tion with a s'elf-propelled' vehicle, the .engine for propelling the vehicle being adapted "to operate the dumping mechanism.

A-further embodiment of the invention resides in the provision of a dumping body which can be operated by the engine of the vehicle tomove into dumping then return to normal position, the tailbody being automatie cally swung into open position when the dumping body to permit the contents of the dumping body to gravitationally discharge therefrom.

In the further. disclosure ofthe invention, reference is to be had drawings constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which-- Figure 1 is a vertical longitudinal sectional view of my device, showing the dumping body in normal position. Fig. 2 is a plan view of the vehicle frame, the dumping body having been removed therefrom. Fig.

which the wheels 12 are mounted to rotate,

.the driving .mechanism 14: being connected to an engine 17 mounted on the forward end of the frame 11, so that when the engine 17 is operated, rotation will be imparted to the wheels 12 to move the vehicle body 10 over the ground.

Journaled on the frame 11 and arranged centrally thereof is a longitudinally extendingscrew rod 20, atoothed wheel 21 being. keyed to the front end of the screw rod and having connection with a toothed wheel 22 through the medium .of a chain 23, the toothed (wheel 22 being keyed to a shaft 24. The shaft 24,

is journaled in bearings 25, secured to the frame 11 and mounted to rotate with the shaft are friction disks 26, 27, adapted to be engaged by a beveled friction wheel 28 mounted to rotate with a shaft 29, having rigidly secured. thereto a toothed wheel 30, the teeth of which are curved and mesh with teeth 31 formed on 'a toothed wheel 32 keyed to the shaft of the engine 17,. adjacent a flv wheel 33 also rigidly secured to the engine shaft. The toothed wheel80 is mounted within a frame 34, having the shaft 29 journaled therein, the mentioned frame 34 being mounted to swing on a bracket 35 secured to the frame of the engine. 1 4

A dumping body 36 hasiwheels 37 edto rotate thereon, the said wheels being arranged to operate over the track 18 .and-

secured to the dumping body 36 at a medial portion thereof are depending brackets 38, rollers 39 being mounted on the lower ends of the brackets 38 and adapted to engage the under sides of the track 18 to retain the dumping body in engagement with the track when the same is moved into dumping position as will be disclosed hereinafter. Mounted to swing on the under side of the dumping body 36, adjacent the brackets 38 are rods i0, pivotally connected to a coupling block 4:1, threadedly mounted on the screw frame .11 is track 18,

mount I of the coupling being adapted to advance the dumping body track 18 members 19 -nected to the lever i2 is a rod 43 to which is v insaeee rod is rotated, the operation block 41 over the screw rod when the screw 36 along the track 18.

Pivotally mounted on the rear endjof the adjacent one of the depending is a lever 42; Pivotallyiconsecured a lug 4A, the front end of the rod being pivotallyconnected to an arm otally mounted on the frame 11 and rovided with an offset arm 46 to which is-connect ed a rod-47 the said 'rod being provided with a coupling member 49, journaled on the "shaft 29-and having connected thereto a rod 50 connected to an operating lever 51. Securedto-the frame 11. and extending upwardly therefrom, of the depending members 19 are hook members 52, the said formed on the under side of the dumping body 36 and to whichv the rods are pivotally connected. r

In the use of my device, the dumping body is in the in F ig..1, when it is desiredto move the dumping body into dumping operating lever 51 is actuated friction wheel 28 from neutral position between the friction disks 26, 27, into engagement with one of the friction disks, preferably the friction disk 27 and thus it will be seenfthat rotation will be imparted to the friction disks to rotate the same in one direction, through the medium of the shaft 29 having the toothed .wheel 80 keyed thereto,

assuming that to move the the mentioned toothed wheel being in mesh with the toothed wheel 32,. rotating with the shaft of the engine 17. Thus at the moment that the toothed wheel 28 engages the friction disk 27, the screw rod 20 will be operated and the dumping body 36 being rod through the me connected to the screw dium of the rods 40 and thecoupling block 41, will be advanced along the track 18 toward the rear end. of the frame 11. Secured to one side of the frame 11, adjacent one of the hook members 52 and extendin outwardly therefrom is a-pin 54 adapte to be engaged byjanarm 55 of a hook 56, pivotally mounted on the rear end of the dumping body 36, the mentioned hook 56 being adapted to. retain a 'tailboard 57 in closed position, the said tailboardbeing denendingly mounted to swing on hangers 58 secured tonthe rear end of the dumping.

body 36. Thus as-the dumping body 86 moves .rearwardly on the track 18, when the pin 54-is engaged by. the arm 55,the tailboard 57 will be unlocked and when the center of the dumping body reaches the and the rollers 39 the friction disk27, 45, p1v-:

Now when the operating lever 51 was'operated to engage the wheel with the lug 4st, through the medium of the rod 4-3 wasmoved to lie in position as mentioned, one of the brackets 53 will engage the lug 44: to move the same rearwardly, thus actuating the rod 43, which in turn swings the wheel 28to neutral position between the disks 26 andf27, thus stopping the tilting mechanism and permitting the engine 17 to run free. When hook members being adapted to be engaged by brackets 53 enga'geme'nt withrthe friction disk 26, thus mparting a reverse-rotation to the shaft 24 andalso to the screw '20, which having so 36 connected thereto by LL-and arms 40, swingsinto horizontal position onthe track and through the rotation of the screw 20, the dumping body will 'be advanced along the track to reassume its nor mal position as shown in Fig, l, the operating lever 51 being then thrown into neutral position to move the wheel 28 out of engage-- 'ment with the friction oisk 26, thus permo mitting the engine 17' to run freev and. pre

the

the coupling block dumping body along the track 18.

From the foregoing description it will be readily seen that a device is provided whereby the dumping body can be moved into dumping position by the action of the engine which is adapted to operate the vehicle, the dumping body being automatically brought toa halt when the same has assumed a dumping position and the tailboard of the dumping body being automatically released to swing into open position at vthe moment that the dumping body assumes a tilting position.

A motor operated dumping wagon including a wheeled frame, a dumping section movably mounted thereon, a motor, a connection intermediate the wheels and motor for propelling the vehicle in the operation of the motor, a motorliy wheel mounted on said connection, means for moving the dumping section to and from dumping position, driving elements for said moving means including spaced. at; ion disks,
